node-fetch currently completely ignoring Content-Length header while consuming response.
Fetch specification about handling Content-Length on server response says almost nothing:
https://fetch.spec.whatwg.org/#concept-http-network-fetch (see whatwg/fetch#67)

On other hand, we have a fetch-node specific extension to limit the size of the response.

Paragraph of placeholder attribute on input element
https://html.spec.whatwg.org/multipage/input.html#the-placeholder-attribute

If a user agent normally doesn't show this hint to the user when the control is focused, then the user agent should nonetheless show the hint for the control if it was focused as a result of the autofocus attribute, since in that case the user will not have had an

Relevant spec sections:

https://html.spec.whatwg.org/multipage/semantics-other.html#selector-ltr

The interesting cases to test are from the definition of "directionality" in HTML:
https://html.spec.whatwg.org/multipage/dom.html#the-directionality

• element with dir="ltr" matches :dir(ltr)
• root element without dir attr

Presumably these should result in a network error. The current specification doesn't state anything and it's not tested either.

See the README for instructions on where to add tests. In the specification the "blob" case of https://fetch.spec.whatwg.org/#scheme-fetch needs updating to handle current URL’s blob URL entry being null.

Under point 6 of the list of steps to take to "ensure pre-insertion validity", as part of an attempt to implement a procedure involving the particular list of steps, I am having trouble unambiguously interpreting the following statement:

parent has an element child, child is a doctype, or child is non-null and a do

What should be the result of new URL("#")?
Browsers return different results and It confuses me.

In my understanding is that new URL("#") should throw a validation error.

https://notifications.spec.whatwg.org/#dom-serviceworkerregistration-getnotifications is manipulating and ES array in parallel steps. It says things like "push that object to objects". How is that supposed to work? Is that using Array.prototype.push? If so, is it using the initial value of that? Even if it does, that can be affected by accessor properties on Array.prototype and in particu

In https://mimesniff.spec.whatwg.org/#parsing-a-mime-type the following step might be clearer if it explicitly said the trailing sequence after " was to be discarded. Might also be better if the example contains a ';' since the step mentions ';'

A <dl class="switch"> in specs represents a switch statement in programming languages. For stylistic reasons we use an arrow character as generated content before each dt.

Example: https://dom.spec.whatwg.org/#dom-node-nodetype

This renders as "rightwards arrow with hook" in screen readers, accor
